Cold-Water Wreck Diving Tips For Caribbean Divers

Cold-Water Wreck Diving Tips For Caribbean Divers
By [http://ezinearticles.com/?expert=Brian_Blum]Brian Blum

Have you done much cold-water wreck diving? If you're used to Caribbean diving, this is a whole different experience. You're going to want to get trained and certified for drysuit, and you'll want to either buy one (check eBay), or find a shop that has one for rent in your size. You can try, but it's really hard to rent a drysuit. If not integrated in your drysuit, you'll also need a hood, gloves, and boots. If the conditions are just right, you might get away with a 7mm wetsuit on shallower dives, but when the water temps at depth get down into the 60s, 50s, and even 40s, you'll be uncomfortable without a drysuit. You'll need open-heel fins (slipper fins don't work well with boots), main and backup lights, a tank light, and a wreck reel. Signaling devices are also a good idea, such as a safety sausage or a whistle. Many wreck divers carry a knife or shears, too, in case of entanglement. If you want to do more serious wreck penetrations, you should train for Wreck certification, too - you'll live longer.

I'm not some serious, expert, North Atlantic wreck diver - I've only done two 2-tank excursions here in the NY Metro Area, and three dives one day in Lake Michigan (which is surprisingly similar), but I've logged over a third of my 91 dives at a cold local quarry called Dutch Springs, plus two at another quarry called Brownstone. I've also done the PADI advanced and Rescue courses, and completed the specialties to earn PADI's Master SCUBA Diver certification, but I have no professional or technical training. I know I'm only a couple of North Atlantic wreck dives ahead of the rank beginners, but from my experience, I have two suggestions...

First, I've seen some rank beginner OW divers get into circumstances beyond their comfort level, and it makes for an unenjoyable (if not dangerous) situation for them. Education and experience will always be an advantage. Don't stop at OW - take AOW certification - it's not a terribly brilliant course of study, but it will give you experience in five different skill areas. U/Nav taught me to check my compass periodically, keep track of my surroundings and landmarks, and measure distance by time, air pressure, or fin kicks; until then, I always used to just blindly follow a dive master like a tour guide - it made me more self-reliant. Wreck taught me to lay and take up a line, ways to avoid stirring up silt, and to be aware of situational hazards. Drysuit and PPB taught me how to better control my buoyancy and trim. Night taught me to use lights and signals, and to be comfortable in low-visibility environments - it made me more confident. Deep, Multi-Level, Altitude, and Nitrox helped me understand more about the physiological effects of diving - awareness of my own body and mind help me prioritize and make better conscious choices, even while stressed, rather than let situations own me.

Most (albeit not all) instructors and many advanced students are also some very good divers, worthy of emulation. Spending more time training with them will improve your diving in ways beyond just the content of the training courses.

Second, take things one step at a time and don't get in over your head. I had already completed Rescue certification, a bunch of the above-mentioned specialties, and 60-total dives, including many in the cold-waters of Dutch Springs and Brownstone before I ever went out on a North Atlantic wreck dive. Visibility was just past arm's length and the water temps at depth were 59-degrees (in late July!). I'd gotten used to such temps at Dutch Springs, but add in low viz, chop, current, a touch of sea-sickness, and the lack of personal space on a "cattle" boat, and you'll see how the stress and task-loading start piling on. Reflecting back on it afterward, I realized that there were a lot of mistakes my buddy and I made on that dive, despite all the training I'd had at that point. Everything turned out well, but tying our wreck reel to the anchor line was a classic newbie error, for example. My buddy was less-experienced, and was relying on me, to some degree, since I had some fraction of the requisite skills for the circumstances. If I had to advise anyone else getting into such diving, I'd say, take it one step at a time:

Get AOW and Drysuit certified

Get a drysuit and get used to it; practice the Drysuit controls, buoyancy, and trim in a pool

Practice more at a protected local quarry or lake

Practice more skills and/or earn specialties for Night, U/Navigation, Deep, and of course, Wreck

Practice night dives

Practice laying, following, and taking up line with a buddy; using a wreck reel is a skill all it's own, and you can even practice it on the silly little wrecks at your local quarry or lake

Do some local night dives at your quarry or lake and try the line exercise again with a buddy - get capable of using a reel and lights at the same time

Once you're good at it, look for some deeper wrecks; everything is more challenging when you're cold and deep - once you're comfortable with that, do it again on a night dive

Last, but not least, before you go on your first serious open-ocean cold-water wreck dive, I can't overstate the value of Rescue training; don't think of it as training to enable you to save lives - think of it as training to make yourself a better, more-aware diver. Before my Rescue class, I used to be just another tourist on a dive boat - now I get my gear squared-up early and I'm more aware of the divers around me. I can observe and help the less-experienced divers, and watch and learn from those more-experienced. An important lesson from the Rescue course is to foresee and avoid situations where rescue would become a necessity.
